Abstract

Low explosive compositions which are more energetic than black powder while at the same time having LOVA characteristics are provided. These compositions contain about 45% to about 66% by weight of a metallic nitrate, the balance being cellulose acetate.

Claims

exact text as granted — not AI-modified
I claim: 
     
       1. An igniter composition having a burn rate exponent of about zero consisting essentially of about 45% to about 66% by weight of a metallic nitrate selected from the group consisting of potassium nitrate and sodium nitrate and about 34% to about 55% by weight of cellulose acetate. 
     
     
       2. A composition according to claim 1 containing about 50% to about 61% metallic nitrate. 
     
     
       3. A composition according to claim 1 wherein the metallic nitrate is KNO 3 . 
     
     
       4. A composition according to claim 1 wherein the metallic nitrate is NaNO 3 . 
     
     
       5. A composition according to claim 2 wherein the metallic nitrate is KNO 3 . 
     
     
       6. A composition according to claim 2 wherein the metallic nitrate is NaNO 3 . 
     
     
       7. In an ordnance device comprising a primary charge selected from the group consisting of propellants and explosives and an igniter charge for igniting said primary charge, the improvement wherein said igniter charge consists essentially of about 45% to about 66% by weight of a metallic nitrate selected from potassium nitrate and sodium nitrate, and about 34% to about 55% by weight of cellulose acetate, whereby said igniter charge has a burn rate exponent of about zero. 
     
     
       8. An ordnance device according to claim 7, wherein the igniter charge contains from about 50% to about 61% by weight of said metallic nitrate. 
     
     
       9. An ordnance device according to claim 7 wherein said metallic nitrate is potassium nitrate. 
     
     
       10. An ordnance device according to claim 7 wherein said metallic nitrate is sodium nitrate. 
     
     
       11. An ordnance device according to claim 8, wherein said metallic nitrate is potassium nitrate. 
     
     
       12. An ordnance device according to claim 8, wherein said metallic nitrate is sodium nitrate.
